"The thing that has changed is the consumers' perspective of what they expect from audio," said Dweezil Zappa, the 36-year-old musician who is performing the music of his late father, Frank Zappa, for new audiences. "I think younger consumers aren't familiar at all with really high-quality audio because for them a CD is the best thing they have ever heard."

"We are trying to add back a layer of quality, a layer of experience that people don't realize that they are missing," said Chris Bennett, president of Audistry.
